Questions
Fair answers before you decide
Clear terms, calm choices, and no surprise invoices.
Do the calculators ever cost anything?
No. All eight calculators work without an account and stay free. Premium only adds scale to the Pixel workspace and exports.
What happens to my charts if I never upgrade?
They stay yours. Charts and projects on the free account remain editable; premium only lifts size, colour, and export limits.
What does Premium add?
Premium includes 200 × 200 Pixel Charts, 64-colour advanced conversion, PDF and SVG export, and 90-day milestone history.
Where is my data stored?
Local projects and charts live on your device. A free account syncs projects to the cloud; images for pixel conversion never leave your browser.
How does billing work, and when can I subscribe?
Choose monthly at $4.99, 3 months at $11.25, or yearly at $25.00. All three are recurring Polar subscriptions with the same Premium access; only the price and renewal timing change.
